Background/aim We previously reported the feasibility of RecoverNow (a mobile tablet-based post-stroke communication therapy in acute care). RecoverNow has since expanded to include fine motor and cognitive therapies. Our objectives were to gain a better understanding of patient experiences and recovery goals using mobile tablets. Methods Speech-language pathologists or occupational therapists identified patients with stroke and communication, fine motor, or cognitive/perceptual deficits. Patients were provided with iPads individually programmed with applications based on assessment results, and instructed to use it at least 1 h/day. At discharge, patients completed a 19-question quantitative and open-ended engagement survey addressing intervention timing, mobile device/apps, recovery goals, and therapy duration. Results Over a six-month period, we enrolled 33 participants (three did not complete the survey). Median time from stroke to initiation of tablet-based therapy was six days. Patients engaged in therapy on average 59.6 min/day and preferred communication and hand function therapies. Most patients (63.3%) agreed that therapy was commenced at a reasonable time, although half expressed an interest in starting sooner, 66.7% reported that using the device 1 h/day was enough, 64.3% would use it after discharge, and 60.7% would use it for eight weeks. Sixty-seven percent of patients expressed a need for family/friend/caregiver to help them use it. Conclusion Our results suggest that stroke patients are interested in mobile tablet-based therapy in acute care. Patients in the acute setting prefer to focus on communication and hand therapies, are willing to begin within days of their stroke and may require assistance with the tablets.

Advanced Therapy

Purpose Hand impairment post-stroke is a very common and important rehabilitation goal for functional independence. Advanced therapy options such as an app. therapy provides repetitive training, which may be beneficial for improving fine motor function. This study aims to evaluate the effect of app-based therapy compared to conventional hand therapy in improving dexterity in individuals with stroke. Methodology In total, 39 individuals within the first year of stroke with Brunnstrom stage of hand recovery IV to VI were randomly divided into three groups. All three groups received 60 min of therapy for 21 sessions over a period of 30 days. Group A received conventional hand therapy; Group B received app. therapy, while Group C received conventional therapy along with the app. therapy. All participants were assessed on the Nine-Hole Peg Test and Jebsen–Taylor Hand Function Test at the beginning and after completion of 21 sessions of intervention. Kruskal–Wallis (H) test and Wilcoxon test were used for statistical analysis. Results All three groups improved on hand function post-treatment. However, Group C demonstrated significant improvement with 16%–58% increase in hand function performance on outcome measures (p < 0.05). Findings Findings of the present study demonstrate improvement in dexterity with the app. therapy and combination therapy, in comparison to conventional therapy alone in individuals with stroke. Originality This experimental study focuses the first time on a structured protocol using an enabling technology adjunct to conventional physical therapy to improve hand function in individuals with stroke, which opens up the further scope in Neurorehabilitation.

The Impact

Background: The effects of musical training on the body in professional musicians remain an understudied area, particularly in reference to understanding and managing orthopedic/neuromuscular deviations and injuries in this population. The purpose of this study was to evaluate hand/finger fine motor function in musicians via physical examination as well as laboratory-based evaluations. Methods: Thirteen healthy noninjured young elite string musicians participated in this study. Performance of musicians was compared with healthy age-matched, sex-matched, and handedness-matched nonmusician controls. Results: Musicians exhibited decreased intrinsic muscle strength compared with controls; however, no change in extrinsic muscle strength was found between groups. No between-group differences in overall force control were found; however, Group × Hand (right vs left) interactions were found in force control. Conclusions: These data suggest that musicians are a unique population with respect to: (1) fine motor control of the hand; and (2) exhibit changes in differential hand use. This suggests cortical reorganization of string musicians, such that this population should be studied separately from typical healthy controls with respect to hand function.

Purpose – Pediatric disorders, such as cerebral palsy and stroke, can result in thumb-in-palm deformity greatly limiting hand function. This not only limits children's ability to perform activities of daily living but also limits important motor skill development. Specifically, the isolated orthosis for thumb actuation (IOTA) is 2 degrees of freedom (DOF) thumb exoskeleton that can actuate the carpometacarpal (CMC) and metacarpophalangeal (MCP) joints through ranges of motion required for activities of daily living. The paper aims to discuss these issues. Design/methodology/approach – IOTA consists of a lightweight hand-mounted mechanism that can be secured and aligned to individual wearers. The mechanism is actuated via flexible cables that connect to a portable control box. Embedded encoders and bend sensors monitor the 2 DOF of the thumb and flexion/extension of the wrist. A linear force characterization was performed to test the mechanical efficiency of the cable-drive transmission and the output torque at the exoskeletal CMC and MCP joints was measured. Findings – Using this platform, a number of control modes can be implemented that will enable the device to be controlled by a patient to assist with opposition grasp and fine motor control. Linear force and torque studies showed a maximum efficiency of 44 percent, resulting in a torque of 2.39±1.06 in.-lbf and 0.69±0.31 in.-lbf at the CMC and MCP joints, respectively. Practical implications – The authors envision this at-home device augmenting the current in-clinic and at-home therapy, enabling telerehabilitation protocols. Originality/value – This paper presents the design and characterization of a novel device specifically designed for pediatric grasp telerehabilitation to facilitate improved functionality and somatosensory learning.

ObjectivesCerebral palsy (CP) is described as a primary disorder of posture and movement; however, intellectual impairment is prevalent in children with CP.AimThe aim of the present study was to examine the association with intellectual level and gross motor function, hand function, type of CP, and the presence of co-morbid disorders in these children.MethodsA total of 107 children with CP were included in the study. Intellectual functions of the children were determined by clinical assessment, adaptive function of daily life, and individualized standardized intelligence testing. Gross motor function and hand function of the patients were classified using the gross motor function classification system and the bimanual fine motor function measurements.ResultsThe mean age of the patients were 8.10 ± 3.43 years (age: 2–16 years). During clinical typing, we observed that 80.4% of the patients were spastic, 11.2% were mixed, 4.7% were dyskinetic, and 3.7% were ataxic. No significant relationship was determined between the type of CP and intellectual functioning (P > 0.05). Intellectual functioning was found to be significantly correlated negatively with both gross motor function and hand functions level (P < 0.001). The factors related to intellectual functioning were neonatal convulsion (x2 = 12.97, P = 0.002), epilepsy (x2 = 29.221, P < 0.001), and speech disorders (x2 = 23.29, P < 0.001).ConclusionsThere is an association between intellectual functioning in children with CP and the degree of motor impairment, neonatal convulsion, epilepsy, and speech disorders. Intelligence assessment should be an essential part of CP evaluation.Disclosure of interestThe authors have not supplied their declaration of competing interest.

And Function

Changes in hand morphology throughout human evolution have facilitated the use of forceful pad-to-pad precision grips, contributing to the development of fine motor movement and dexterous manipulation typical of modern humans. Today, variation in human hand function may be affected by demographic and/or lifestyle factors, but these remain largely unexplored. We measured pinch grip strength and dexterity in a heterogeneous cross-sectional sample of human participants (n = 556) to test for the potential effects of sex, age, hand asymmetries, hand morphology, and frequently practiced manual activities across the lifespan. We found a significant effect of sex on pinch strength, dexterity, and different directional asymmetries, with the practice of manual musical instruments, significantly increasing female dexterity for both hands. Males and females with wider hands were also stronger, but not more precise, than those with longer hands, while the thumb-index ratio had no effect. Hand dominance asymmetry further had a significant effect on dexterity but not on pinch strength. These results indicate that different patterns of hand asymmetries and hand function are influenced in part by life experiences, improving our understanding of the link between hand form and function and offering a referential context for interpreting the evolution of human dexterity.

<P>Background: The radial artery (RA) is increasingly being used as a conduit for coronary artery bypass grafting. Previous studies have demonstrated that there is no significant deterioration in hand function in the long term. The aim of this study was to assess whether removal of the RA caused any alteration in the function or power of the hand 5 days postoperatively that would affect the patient's ability for self care on returning home. </P><P>Methods: A consecutive series of 37 patients undergoing RA harvesting was assessed over a period of 12 months from August 2000 to July 2001 as part of a prospective controlled trial. Grip power and fine motor skills in the operated hand were assessed preoperatively with an elasticated grip strength tester and an 18-hole peg board. This test was repeated 5 days postoperatively. The results were analyzed with a paired-sample t test to assess whether there was a significant difference between preoperative and postoperative hand function. </P><P>Results: The analysis showed that there was no statistically significant difference in fine motor function or grip power following surgery to harvest the RA. </P><P>Conclusion: This study provides evidence to suggest that the RA can be safely harvested for use as a conduit in coronary artery bypass grafting, with no significant short-term deterioration in hand function.</P>

Auditory Cueing

Background and purpose - Parkinson’s disease with cardinal feature of bradykinesia is a movement disorder. The effect of cueing in disorders like parkinsons patients ,stroke, spinal cord injury for improving motor skills and gait and lower limb functions have long been investigated by the Researchers, but there are dearth of studies evaluating the effect of cueing on fine motor skills in patients with parkinson’s disease. Hence this study tries to investigate the effect of auditory cueing on fine motor skills in Parkinson’s disease. Methodology - 25 diagnosed Parkinson’s patients having primary level of education, with mean age 72±5 yrs in Hoehn and Yahr stages 1 to 3 of disease and MMSE score above 24 were included in the study. Two groups were formed; one group performing activities with auditory cueing and other group performing activities without auditory cueing. Scores were calculated using Jebsen Taylor Hand Function Test. Results - Mean values of pre and post intervention timings on Jebsen Taylor Hand Function Test were calculated. Group with auditory cueing showed improvement in total sores of subtests of Jebsen Taylor Hand Function Test with mean and standard deviation (58.51±2.69) seconds in dominant hand and (54.59±2.43) seconds in non-dominant hand, whereas, Group without auditory cueing showed improvement in total sores of subtests of Jebsen Taylor Hand Function Test with mean and standard deviation of (13.39±2.07) seconds in dominant hand and (13.52±1.96) seconds in non-dominant hand. Conclusion- Auditory cueing is proved to be an effective method in improving fine motor skills in patients with Parkinsons disease.
